Rafael, I had exactly the same problem over here. In my case, I used Tomcat servlet container to run Axis2 server (JAX-WS Web Services).
In this case, when I tried to shutdown my server, It throw messages accusing instances that cannot be deallocated. I solve that problem with an Amila's blog post, http://amilachinthaka.blogspot.com/2009/05/improving-axis2-client-http-transport.html. Good luck. Bruno Simioni.
